Link shortening services are great for squeezing long links into tiny places. A shortened link is a URL with fewer characters that redirects to a longer destination URL. Many reasons exist for wanting to shorten a link. They are easier to type and remember and are a method for tracking clicks. Shortening a link masks the original link, and its actual destination becomes unknown. The need to check shortened links for safety arises from this circumstance.

Short links are easier to share than long links. Websites often append links with query strings. A query string added to a link can extend the length of a link by scores or even hundreds of characters, a displeasing aesthetic. Links of that size are often truncated or divided when they reach the recipient. Such links may point to useless, invalid locations. Shortening services remedy the long link issue by reducing them into 10 to 30 character URLs.


Shortened links are also useful in applications that impose character limits. Twitter imposes a 280 character limit per message. They created the link-shortening service to shorten links shared using its platform. Shortened links in tweets have a 23 character limit. The links use the domain name. This allows Twitter to count the clicks on each link and to check it for malicious content. Twitter checks shortened links for safety against a list of potentially harmful websites. If a link points to malicious content, Twitter displays a warning message.

Some link shortening services provide opportunities to preview the destination of a shortened link. If you want to preview the destination link of a link, add a plus sign to the end of their shortened link. For example, preview the destination link of by visiting instead. A preview page displays on the site with information about the shortened link. checks its shortened links for malware using data from independent sources.
